[PATCH] RISC-V: Add riscv-*-* configure support, and minor cleanup.

[Jim Wilson]

Support for riscv as a CPU has been added to upstream config.sub, so we need
to support it in binutils now.  This adds riscv as an alias for riscv32.  This
also fixes a consistency problem, where bfd accepted riscv32 and ld accepted
riscv32*.  It should be riscv32* everywhere for now, and same with riscv64*.

Tested with riscv{32,64}-{elf,linux} and riscv-elf builds and make checks.
There were no regressions.

Committed.

Jim
